To follow up on this a little bit this one: onmessage(Reader reader) only works also on the "whole" message that is weird because you don't have i think really this support: onmessage(Reader reader, boolean lastPart) (at least that is not specified here: https://javaee-spec.java.net/nonav/javadocs/javax/websocket/OnMessage.html) But in a reader that sounds just weird, the reader should just block until all parts are feeded to the reader.. But that also doesn't work it fails. So what is really the point of the reader param in this scenario? -- Johan Compagner Servoy
